Using Fourier-Mukai techniques we associate certain jumping schemes to such sheaves and completely classify such loci. We give examples of applications to the enumerative geometry of T and show that no smooth genus 5 curve on such a surface can contain a g^1_3. We also describe explicitly the singular divisors in the linear system |2l|.", "revisions": [ { "version": "v2", "updated": "2011-07-18T18:20:32.000Z" } ], "analyses": { "subjects": [ "14F05", "14N10", "14N20", "14J60", "14D20", "14K30", "14C20" ], "keywords": [ "enumerative geometry", "fourier-mukai approach", "study twisted ideal sheaves", "smooth genus", "fourier-mukai techniques" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1107.2549M" } } }
